tdm login menu > Session type

I have uninstalled Mate and Plasma using apt (because I previously installed using apt).  There is a residual item for each of mate and plasma in the tdm login display manager.  This state must be held on disk somewhere.  The problem is where to find it.  Can anybody tell me where it is?

Run terminal commands
$ dpkg --get-selections | grep -v deinstall | grep plasma
$ dpkg --get-selections | grep -v deinstall | grep mate
to list installed packages in question.

Re: tdm login menu > Session type

thanks a lot.  this worked a treat.  i removed all packages using apt beginning with plasma*.  I still have the package libkf5plasma5 remaining which is a plasma library and runtime components based upon KF5 and Qt5.  if i do an apt --autoremove remove on this, will it break my system? i.e. should I leave it alone?

Some installed applications may depend on plasma packages, so if you remove them it will remove dependencies as well. However you can safely run:
$ sudo apt autoremove
it will not break your system in anyway.
